They possess a certain degree of automation and can perform various industrial processing and manufacturing functions using their own power and control capabilities. Industrial robots are widely used in various industrial sectors such as electronics, logistics, and chemicals.

[0004] The aforementioned application document describes a process where a push cylinder is activated to move the lower mold below the upper mold, and the upper mold moves down to complete the stamping operation. During the stamping process, waste chips may be generated, and the stamping head may be damaged due to high temperature. Utility Model Content

[0005] This utility model proposes a robot for machining, which solves the problems in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model relates to a machining robot, comprising an electric platform, a robotic arm mounted on the top of the electric platform, a hydraulic cylinder mounted on the end of the robotic arm furthest from the electric platform, a movable plate fixedly connected to the output end of the hydraulic cylinder, a motor mounted on the bottom of the movable plate, a rotating shaft fixedly connected to the motor via its output shaft, a drill bit fixedly connected to the bottom of the rotating shaft, and a cooling mechanism mounted on the bottom of the movable plate. The cooling mechanism includes a bevel gear A, a support plate, a pressure chamber, and a water tank. The bevel gear A is fixedly connected to the surface of the rotating shaft, and the top of the support plate is fixedly connected to the bottom of the movable plate. A rotating rod is rotatably connected through the side of the plate. One end of the rotating rod is fixedly connected to a bevel gear B, and the other end is fixedly connected to a rotating gear. The bottom of the pressure chamber and the water tank are both fixedly connected to the top of the moving plate. A return spring is installed inside the pressure chamber. A piston rod is slidably connected inside the pressure chamber through the return spring piston. A toothed rod is fixedly connected to the bottom of the piston rod. A water suction pipe is rotatably connected through the rear end of the pressure chamber. A water outlet pipe is rotatably connected through the side of the pressure chamber. Both the water suction pipe and the water outlet pipe are equipped with one-way valves. An anti-rebound mechanism is installed on the side of the support plate.

[0008] Optionally, the bevel gear A is initially meshed perpendicularly with the bevel gear B, and the number of teeth on the bevel gear B is twice that of the bevel gear A. When the bevel gear A rotates, it will drive the bevel gear B to rotate, and the bevel gear A rotates twice, which will only drive the bevel gear B to rotate once.

[0009] Optionally, the rotating gear is an incomplete gear, and the teeth on the rotating gear are initially engaged with the teeth on the rack. At the beginning, the rotation of the rotating gear will drive the rack to move downward.

[0010] Optionally, the end of the suction pipe away from the pressure chamber is connected to the water tank through and fixedly, and the one-way valve inside the suction pipe is unidirectionally open to the inside of the pressure chamber. When a negative pressure is formed inside the pressure chamber, water will be drawn from the water tank through the suction pipe.

[0011] Optionally, the end of the water outlet pipe away from the pressure chamber is close to the drill bit, and the one-way valve inside the water outlet pipe is unidirectionally open to the outside of the pressure chamber. When the water in the pressure chamber is squeezed, the water inside will be sprayed out through the water outlet pipe.

[0012] Optionally, the anti-rebound mechanism includes a deceleration block, a rotating shaft, and a limiting rod. The deceleration block is fixedly connected to the side of the support plate, the rotating shaft is rotatably connected to the side of the piston rod, a contact plate is fixedly connected to the end of the rotating shaft away from the support plate, an elastic rope is fixedly connected to the top of the contact plate, the end of the elastic rope away from the contact plate is fixedly connected to the side of the piston rod, and the limiting rod is fixedly connected to the side of the piston rod.

[0013] Optionally, the end of the contact plate away from the piston rod is close to the side of the support plate, and the end of the limiting rod away from the support plate is close to the bottom of the contact plate. When the contact plate moves, it will contact the deceleration block, and the limiting rod prevents the contact plate from deflecting downward.

[0014] Optionally, the deceleration block is semi-cylindrical in shape and made of rubber. When the contact plate is squeezed against the semi-cylindrical rubber deceleration block, it will generate a large resistance.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. This utility model is equipped with a cooling mechanism, which enables the motor to drive the rotating shaft to rotate. When the rotating shaft drives the drill bit to rotate and cooperate with the robotic arm to perform drilling work, the rotating gear, rack, pressure chamber and other components will work together to make the water suction pipe draw water from the water tank and spray it onto the drill bit through the water outlet pipe to cool it down and reduce dust, preventing the drill bit from overheating and the debris from obstructing the view.

[0017] 2. By incorporating an anti-rebound mechanism, the piston rod moves up and down during the opening process. Through the cooperation of components such as the rotating shaft, contact plate, and speed reduction block, the return spring slows down the downward movement of the piston rod as it moves downward to restore its original position. This prevents the piston rod from bouncing back and forth due to the return spring, thus improving the overall stability of the device. Attached Figure Description

[0029] Example 1

[0030] Reference Figures 1-5This is the first embodiment of the present invention, which proposes a robot for machining, including an electric platform 1. A robotic arm 2 is mounted on the top of the electric platform 1. A hydraulic cylinder 3 is mounted on the end of the robotic arm 2 away from the electric platform 1. A movable plate 4 is fixedly connected to the output end of the hydraulic cylinder 3. A motor 5 is mounted on the bottom of the movable plate 4. A rotating shaft 6 is fixedly connected to the motor 5 through its output shaft. A drill bit 7 is fixedly connected to the bottom of the rotating shaft 6. A cooling mechanism 8 is mounted on the bottom of the movable plate 4. The cooling mechanism 8 includes a bevel gear A81, a support plate 82, a pressure chamber 86, and a water tank 811. The bevel gear A81 is fixedly connected to... On the surface of the rotating shaft 6, the top of the support plate 82 is fixedly connected to the bottom of the movable plate 4. A rotating rod 83 is rotatably connected through the side of the support plate 82. One end of the rotating rod 83 is fixedly connected to a bevel gear B84. In the initial state, the bevel gear A81 meshes perpendicularly with the bevel gear B84, and the number of teeth on the bevel gear B84 is twice that of the bevel gear A81. When the bevel gear A81 rotates, it will drive the bevel gear B84 to rotate, and the bevel gear B84 will only rotate once when the bevel gear A81 rotates two revolutions. The other end of the rotating rod 83 is fixedly connected to a rotating gear 85. The bottoms of the pressure chamber 86 and the water tank 811 are both connected to the movable plate 4. The top of plate 4 is fixedly connected. A return spring 87 is installed inside the pressure chamber 86. A piston rod 88 is slidably connected inside the pressure chamber 86 via the return spring 87. A gear 89 is fixedly connected to the bottom of the piston rod 88. The rotating gear 85 is an incomplete gear, and its teeth initially mesh with the teeth on the gear 89. Initially, the rotation of the rotating gear 85 causes the gear 89 to move downwards. A suction pipe 810 is fixedly connected through the rear end of the pressure chamber 86, and an outlet pipe 812 is fixedly connected through the side of the pressure chamber 86. The suction pipe 810 and the outlet pipe 812... Each part is equipped with a one-way valve. The end of the suction pipe 810 away from the pressure chamber 86 is connected to the water tank 811 through and fixedly connected. The one-way valve in the suction pipe 810 is unidirectionally open to the inside of the pressure chamber 86. When a negative pressure is formed in the pressure chamber 86, water will be drawn from the water tank 811 through the suction pipe 810. The end of the outlet pipe 812 away from the pressure chamber 86 is close to the drill bit 7. The one-way valve in the outlet pipe 812 is unidirectionally open to the outside of the pressure chamber 86. When the water in the pressure chamber 86 is squeezed, the water inside will be sprayed out through the outlet pipe 812. The side of the support plate 82 is equipped with an anti-rebound mechanism 9.

[0031] In this embodiment, when the overall device is used, the electric platform 1 drives the robotic arm 2 to rotate, the motor 5 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the drill bit 7 to rotate, and the rotating drill bit 7 works in conjunction with the robotic arm 2 to perform drilling. The rotation of the rotating shaft 6 also drives the bevel gear A81 to rotate, the rotation of bevel gear A81 drives the rotation of bevel gear B84, the rotation of bevel gear B84 drives the rotating rod 83 and the rotating gear 85 to rotate. The rotation of the rotating gear 85 initially drives the rack 89 to move downward, the downward movement of the rack 89 drives the piston rod 88 to move downward, and the return spring 87 is pulled. When the piston rod 88 moves downward, it creates a negative pressure in the pressure chamber 86. This negative pressure draws water from the water tank 811 through the suction pipe 810. When the rotating gear 85 rotates to the toothless part and disengages from the gear 89, the return spring 87 rebounds, causing the piston rod 88 and gear 89 to move upward. This compresses the water in the pressure chamber 86, causing it to spray out through the water outlet pipe 812, thus forming a circulation. The water is then sprayed onto the drill bit 7 through the water outlet pipe 812 for cooling and dust reduction, preventing the drill bit 7 from overheating and preventing debris from obstructing the view.

[0032] Example 2

[0033] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the anti-rebound mechanism 9 includes a deceleration block 91, a rotating shaft 92, and a limiting rod 95. The deceleration block 91 is fixedly connected to the side of the support plate 82. The rotating shaft 92 is rotatably connected to the side of the piston rod 88. A contact plate 93 is fixedly connected to the end of the rotating shaft 92 away from the support plate 82. An elastic rope 94 is fixedly connected to the top of the contact plate 93. The end of the elastic rope 94 away from the contact plate 93 is fixedly connected to the side of the piston rod 88, limiting... Rod 95 is fixedly connected to the side of piston rod 88. The end of contact plate 93 away from piston rod 88 is close to the side of support plate 82. The end of limiting rod 95 away from support plate 82 is close to the bottom of contact plate 93. When contact plate 93 moves, it will contact deceleration block 91. Limiting rod 95 prevents contact plate 93 from deflecting downward. Deceleration block 91 is semi-cylindrical in shape and made of rubber. When contact plate 93 is squeezed against semi-cylindrical rubber deceleration block 91, it will generate greater resistance.

[0034] Compared to Embodiment 1, further, when the piston rod 88 moves downward, it will drive the contact plate 93 to move downward. The contact plate 93 will contact the deceleration block 91 on the side of the support plate 82. At this time, the bottom of the contact plate 93 will be deflected upward by the force and will not generate too much resistance with the deceleration block 91. Then the elastic rope 94 will drive it to return to its original position. When the return spring 87 rebounds and drives the piston rod 88 to move upward to return to its original position, the contact plate 93 will contact the deceleration block 91 again. At this time, under the action of the limiting rod 95, it cannot deflect downward. The contact plate 93 will squeeze with the deceleration block 91 and generate greater resistance, thereby preventing the return spring 87 from causing the piston rod 88 to bounce back and forth, thus improving the stability of the overall device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
